    Put them a good bit above the connection (dropline, spout) they are near, add a loop in the line, and put a tin can over them. Those things will help reduce the chances of failure, but you'll still...

    I agree with Dave. 1.25-1.5" would be better. Less chance of niter chunks clogging the pipe and stopping the flow.

    Although sanitary connections are more expensive, they are far easier to take...

    In terms of sanitation, longer than 5-10 minutes is not better (or worse). Shorter than that and the sanitation efficacy drops off (you won't have achieved the full effect). Longer than that...

    Might work well, at least for a while. Depends upon how much heat and steam it gets. Most of these small fans have a thermal cut-off switch, which shuts it off when it gets too hot. Over time the...

    Short contact time (as happens by pulling a solution in under vacuum) is fairly ineffective. Hardly worth (or not work economically) doing.

    You can either pump in a solution from the bottom, or...

    1:20 standard bleach (5.25% sodium hypochlorite) to water solution is recommended with a minimum contact time of 5-10 minute. Follow this with a copious rinse of fresh water. As long as you rinse...

    Crew is out doing minor adjustments to several experiments, cutting up fallen limbs/trees after the last few wind storms, and clearing mainline paths for a 1,000 tap install for early next summer. ...

    You are correct. What I was describing was the situation with a single mainline system. Conditions are different for a dual (wet-dry) mainline system. For at least the wet-dry component of that...

    Joe is spot on. Go with the 1" pipe. It is far more forgiving as well. You are always aiming to have AT MOST 1/2 of the pipe full of liquid during peak flows. That is under ideal installation...

    You're welcome.

    To continue the analogy, in the case of sagging lines, you've pushing and pulling the sap up and down a series of small hills. Takes energy to do that.

    It is almost impossible to tell what is happening on in terms of sap movement by looking at the lines if they have air and sap in them since they intermix and the sap slides past the air in both...

    Have the temperature-based auto-start turn on a timer with a heat-lamp which runs for 30-60 min, then have another timer start the pump. Just set it to turn on a few degrees earlier.

    To help with terminology, the 3/16" "mainline" you refer to is actually the "lateral line".

    And maybe less need to clean quite as much. Typically with a multiple front-pan setup you would remove the front-most front-pan, slide the rear front-pan forward, then put the new pan in the rear. ...

    Sure, but that'll only give you a general indication of what the grade and final invert level will be. With experience you can probably guess pretty close judging by the sap quality.
